s Claims.

This invention relates to cocky forming and cutting machines, and particularly to a machine capable of producing sliced or cut cookies of various shapes and thicknesses and also strip cookies.

One of the objects of the invention is to produce a machine having easily adjustable means for determining the thickness of the cookies produced thereby, said means providing finely graduated adjustments within a wide range.

Another object is to provide a machine in which a single operating handle actuates the dough feeding mechanism and the cutting mechanism.

Another object is to provide' means for interchanging and mounting diiierent Idies used for forming cookies, said means being located so as to be easily accessible to the operator.

In that embodiment oi the invention shown `in the drawings, a pair of spaced apart, vertical side members l0, Ill support the rolls II, II between them, said rolls having hubs l Z of reduced diameter, rotatably mounted in said side members Ill, I. At one side of the machine, said hubs I2 have xedly mounted thereon, outwardly of the side member I il, a pair 0i gears I3, I4 in mesh with each other, so that when one roll is driven in one direction, the other roll will rotate in the opposite direction.

A ratchet device indicated as a whole at I is also mounted on the hub i2 of the roll II on which the gear I3 is mounted. The ratchet comprises an inner ring I6 having teeth I'l on its periphery, an outer ring I 8 in which are mounted V32. l 35 and intoa recess in the die 32 at each' end spring pressed detents I9. The inner ring I6 is integral with or is fixed to the gear I3 in any suitable manner. An actuating lever 20 is mounted on the outer ring and is secured thereto as indicated at 22. A disc 2| retains the ring I8 by means of the nut and bolt 23 against the gear I3 and inner ring I6 of the ratchet. A plate 24 retains the detents i9 in position in the ring ,I 3.

When the actuating lever 26 is moved clockwise, the outer ring I8 of the ratchet also moves clockwise andthe detente I9 engage the teeth Il of the inner ring I6, locking the rings together and thereby causing the gear I3 and roll II to be rotated clockwise. The roll II' will be rotated counter-clockwise by the meshing 0f the gear I4 with the driven gear I3. When the actuating lever 20 is moved counter-clockwise, the outer ring I 8 of the ratchet slips over the toothed inner ring and no movement is imparted to the gear I3 or roll Il.

On the periphery of the outer ring I8 is a notch which forms a tooth 25 for a purpose to be explained. `A stop pin 26 `is removably positioned in the periphery of the outer ring I8 limiting the movement of said ring between a pair of stops 2l, 23adjustably positioned on a screw threaded rod 29 mounted iixedly on the side member I Il by bolts 3i). The stops 2l, 28 control the extent of rotative movement of the ratchet I5 and consequently control the dough feeding movement of the rolls I I, II', between which dough is fed from a hopper 3 I.

Closely beneath the 4rolls I I, II is a forming die indicated as a whole at-32. As shown in Figs. 5 and 6, the die is provided with round holes 33 through which the dough passes, the ribs 34 coniining the dough as intended. The die is detachably mounted by means of a pair of angle rails 35, 35 mounted adjacent the inner surfaces of the side members I, I0',by bolts 36 and 3l. The bolt 36 has a hook end 38 which engages one end of the rail 35. The upper end of the bolt 33 extends through a rod or bar 39 and is adjustably secured in position by a wing nut .46. The bolt 37 has a head il which `retains the rail '35, and the free end of the bolt 3'! extends through a support 42 on the side member and is adjustably secured by a Wingnut 43. Usually only the bolt..36 need loe-detached to allow the rail S5 to be lowered at one end suiiiciently toV remove the die 32 for cleaning purposes or for interchanging dies.

The rails are bent upwardly near Vone end, as

shown in Fig. 5; which aids in positioning the die A screw 45.- which extends through the rail serves to hold the die stationary in use, as shown in Figs. and 1.

A rod or bar 45 similar to the rod or bar 39 extends between the side members I0, Ill', and said bars 39 and 45 are rmly secured to the side members by plates 39 and 45 bolted to said members, and provide a strong frame for the rolls, .die and operating mechanism.

The cocky cutting means (Figs. 3 and 5) comprises a cutter frame Yconsisting of a series of rods 46, connected together by cross rods 41, 48, near one end. A cutter wire 49 is connected to said rods 46 at their other ends. The cross rod 48 is pivotally mounted at its ends in a pair of levers 56, reinforced by an L-shaped member 5I.

Each lever 56 at its lower end is pivotally mounted on a shaft 52 which extends through the side members I8, I0', near the bottom of said side members. Pivotal movement of the lever 56--5I transmits horizontal movement to the cutter wire`49 across the lower face of the die 32 as will be more fully explained hereinafter. hook ends 54, are attached to the rod 45 by any suitable means 55, the hook ends 54 being adapted to engage the cross rod 48 of the cutter frame in one of its positions.

A slotted bracket 56 extends rigidly upwardly, as best shown in Figs. 1 and 2, from one end of the cross rod 48. A coiled spring 51 surrounding a rod 58 is attached at one end to the bracket 56 by any suitable means 59. At its other end, the spring bears against an apertured plate 60 Vsecured to the side member I0. The rod 58 is also attached to the bracket 56 and at its free end extends through the aperture in the plate 6I) to a lgreater or lesser extent, depending on the position of the cutter frame and bracket 56.

A lever or pawl 6i is pivotally connected at 62 to the part 5I of the lever 58. Its hooked end 63 is adapted to engage the tooth 25 of the ring A pair of cutter frame stops 53, having upwardly to the limit of its movement, as in Fig. 1, the end 63 of the lever 6I will fall into the notch which forms the tooth 25 on the ring I8. Then the actuating lever is moved downwardly, counter-clockwise, and the lever 20 rotates the outer ring I8 with it, causing the lever 6I (engaged by the ratchet tooth 25) to be pulled toward the left, from the position shown in Fig. 1 to the dotted line position of Fig. 2. The lever 6I draws the pivotally mounted lever 50-5I toward the left, as shown in Fig. 2, and this action accomplishes two things. It compresses the spring 51 between the bracket 56 and the fixed plate 68. It also moves the cutter frame 46-48 to the left so that the cutter wire 49 passes across the bottom of the die 32 as shown in Fig. 5, cut-r ting the dough into flat cookies having the hori`V zontal cross section of the openings 33.

When the actuating lever 26 has been moved downwardly to the dotted line position of Fig.V

. 2, the lever 6I begins to release from the tooth i8. The pawl 6I is retained or guided by a bent arm 64 attached to the side member I0 as indicated at 65 (Figs. 1, 2 and 3) In Figs. 8 and 9, I have shown a modified formV of die 66'adapted for producing strip cookies. It has openings 61 corresponding to the vertical cross section of the strip to be produced. The end construction 68 and the dimensions of the die 66 are such that said die can be interchanged with the die 32 and be mounted on the rails 35. It will be understood that the apertures 33 in the dieA 32 correspond with the horizontal cross section of the cookiescut from the dough which passesy through said openings. n

The operation of the machine is as'follows: Assuming the die 32 is in proper position on the rails' 35, the stops 21 and 28 are adjusted on the rod 29 according to the thickness of cookies desired, and dough is placed in the hopper 3| above the rolls II, II. We will assume that dough has 'beenpassed downwardly between the rolls so that' it is ready to emerge from the openings 33 in the die 32` Then the actuating lever 26 is moved upwardly, thatV is, rotated clockwise, thereby rotating the ratchet members I8 and I6 together, as well as the gear I3 which drives the gear I4, and their respective rolls II, Il'. YThe lever 26 can be moved only to the extent permitted I by the stops 21 and 28 between which is oonned the stop pin 26 on the ratchet ring I8. This movement of the rollscauses a proper amount of dough to pass through the openings 33 in the die.

When the actuating lever 20 has been moved 25 and a slight further counter-clockwise move' ment completes the release and then the spring'y 51 expands and moves the lever SII- 5I and con nected cutter frame 46-48 to the right, that is, the initial position shown in Fig. 1.

It will be understood from the foregoing that only two actuations of the lever 20 are necessary' for each cycle of operations: limited movement in a clockwise direction to drive the rolls and feed dough through the die 32, and reverse movement of the lever 20 for cutting the dough and restoring the cutter frame and other parts to initial position.

It will also be understood that the connection 59 between the spring 51 and the bracket 56 is adjustable and this arrangement serves to vary the cutting relationship between the cutting wire and the bottom of the die. Adjustment of the connection 59 will always keep the cutting wire in correct position.

When it is desired to produce strip cookies, the die 66 is substituted for the die 32, and the stop pin 26 is removed from the ratchet ring I8. The pin 26 can be mounted in the arm 64 in such position that it serves as a support for holding the lever 6I out of engagement with the tooth 25 of the ratchet ring I8. Then the lever 26 can be rotated clockwise without being limited by the stops 21 and 28, and the cutting mechanism will be inoperative. Dough will be fed in `long strips through the die 66 and the strips may fall directly into baking pans which may be moved between the side members I8, I8 beneath the die 66. l

Changes may be made in details of construction without departing from the scope of my invention.
